Vlotho ([ˈfloːto] ⓘ) is a town in the district of Herford, in North Rhine-Westphalia, Germany.

Vlotho borders on Herford and Löhne in the west, Bad Oeynhausen and Porta Westfalica (both Minden-Lübbecke district) in the north, Kalletal in the east, and Lemgo and Bad Salzuflen (both Lippe district) in the south.

In 1248, Vlotho gained the official status of a city, but this was subsequently lost due to depopulation resulting from pestilence and war.

[citation needed] During the Thirty Years War, on 17 October 1638 Vlotho was the site of a battle, which resulted in a victory for an Imperial army under the command of Field Marshal Melchior, Count of Hatzfeldt over a Palatinate-Swedish army under the command of Charles Louis of Palatine.

In 1875, Vlotho station was constructed, and in 1928, a bridge replaced the ferry across the Weser river.
